Problem loading elements 2025 from elements 2014

I tried to import my photos to elements 2025 from organiser in elements 2014 but it said I had 500000 images (not true) and took 48hrs to load them. None of my albums moved across and Im left with lots of duplicates and not at all organised. Also when I try to scroll through them the program keeps quitting. I have a new macbook air.
